Plot hole: Isn't it rather strange that nobody outside the Howard family's small town expresses any interest in the confirmed discovery of a new human sub-species, the only one on the planet? Wouldn't it be more likely that their little backwater town would be inundated with every press and scientific organisation on earth, and that the Howard family would be the centre of the greatest publicity carnival of all time?
Plot hole: When the cop shows Pam the newspaper clippings they include what look to be fresh photos of the real Jason from the events of Part IV, yet no photographer is ever seen taking pictures of Jason alive in the previous films and most likely wouldn't live long enough to publish the photo.

Plot hole: When Schaeffer, McFee, and Fergie drive to the Lapp farm to kill John, the car stops on top of a hill. Then it reverses a bit to be out of sight from the farm. But then the formerly careful guys get out and walk down the open road, sporting their guns like in an Italo western. (01:28:30)NancyFelix
Plot hole: When Fitz-Hume and Millbarge disguise themselves as aliens in order to distract the mobile launcher crew, where exactly did they get the foil they are wearing? Except for the satellite dish Millbarge wears on his head, no parts of their code transmitter can have been used or the thing would be of no further use, and it is very unlikely that either of the two spy groups brought any of the foil along.
Plot hole: When Diana turns up at her director friend's house she finds it crawling with cops as his girlfriend Christie has been murdered and the house is now a crime scene. She explains she lent Christie a coat and is there to pick it up - and a cop helpfully finds it on the floor and hands it to her. Are we to believe that a homicide policeman will hand over an artifact from a murder scene to an unidentified woman without making any attempt to confirm her identity, or even if the coat is even hers!? They don't even ask.
Plot hole: When Freddy takes over Jesse's body at the party, there are several people watching through the patio doors when he confronts Lisa. None of these people ever make a sound, even when they see Lisa have a knife fight with a horribly disfigured man with long knives coming out of his fingers. The other party goers are completely oblivious to Freddy's presence until he comes jumping through the glass doors.Twotall
Plot hole: When Bond and Tibbett break into the underground lab and find the device which drugs the racehorses, you can see that it has a large light emitting diode (LED) on the top of it. What possible use would that be, since the device is implanted in the horse's leg, and is supposed to be covert? (00:37:20)Madstunts
Plot hole: After Frank and Freddie accidentally release the trioxin gas, there are several shots of the gas entering a return air vent and traveling through the heating, ventilation and air conditioning system belonging to the warehouse. Finally the gas exits into the freezer directly on to a hanging cadaver. This room was previously confirmed as a freezer and would have had its own self contained refrigeration system with its own ventilation system. Typical freezer doors also seal as they close. The cadaver would have never come into contact with the trioxin gas and would have never reanimated.
Plot hole: In the airport scene when Chance runs through security after Cody, he is chased by an airport police officer. During later shots you can see the officer in hot pursuit not far behind Chance. Yet when he gets to the exit gate beside the washroom where Cody was hiding, Chance spends several seconds scanning the gate area before setting off to the washroom. Surely the airport officer would've long caught up to Chance by then, but instead the same officer does not re-appear until some time later after Chance has intercepted Cody in the washroom.
Plot hole: When Dudikoff gets Ninja training from the old gardener before his final confrontation with Black Star Ninja, the gardener says "The time has come for your final lesson" and then introduces him to the throwing star and the ninja sword. If this is the final lesson and he's only being introduced to these weapons now, how come Dudikoff used these weapons successfully earlier, against about 15 ninjas in the fight at the warehouse trap?
